Ruby Color Generator

This gem randomly generates very distinct colors with consistent lightness and saturation.

If you are using these colors as background colors, consistent lightness lets you use the same foreground color for each. Consistent saturation lets you avoid mixing pastels with vibrant colors, etc.

Usage

require 'color-generator'

Generate colors using the HSL color representation:

generator = ColorGenerator.new saturation: 0.3, lightness: 0.75
color1 = generator.create
# => "cfd2ac"
color2 = generator.create
# => "cbacd2"

Generate colors using the HSV color representation:

generator = ColorGenerator.new saturation: 0.3, value: 1.0
color1 = generator.create
# => "f7b3ff"
color2 = generator.create
# => "b3ffe0"
